Yves Saint Laurent sponsored last night’s star-studded Metropolitan Opera House premiere of Le Comte Ory, and the celebs in the crowd put on their YSL best for the occasion. Mary-Kate and Ashley Olsen (shown) accessorized their textured black dresses with sunglasses from their own line, The Row. Emmy Rossum went with a spring green frock and purple pumps for the event. “I like the mixing of the colors,” she told us. “It feels kind of ’70s, Moroccan fun.” Click through the gallery to see what Claire Danes, Olivia Munn, Claudia Schiffer, and more wore last night.
